3D printing, one of the most popular methods for creating new components through the deposition of material in layers, is used across a wide range of products, particularly in the aerospace and medical fields. 3D printing focuses especially on thermoplastic materials, allowing for the easy production of functionally graded products. The manufacturing parameters used in 3D printing vary, significantly affecting the mechanical properties of the printed items. In this study, PLA, PETG and ABS samples were printed using a high-speed 3D printer in accordance with ASTM standards. Tensile, hardness, surface roughness and water absorption tests were performed to determine the material properties of the produced samples. The results provide a comparative analysis of the most preferred thermoplastic materials (PLA, PETG and ABS) and serve as a production guide for high-speed printing. The maximum stress for PETG specimens was found to be 51.3 MPa, while for PLA it was 48 MPa and for ABS specimens 42.8 MPa. In addition, the average hardness of the top surface of the PETG sample was found to be the highest with 76 Shore A, while 69 Shore A and 63 Shore A values were observed for PLA and ABS samples, respectively. Finally, the roughest surface in the untreated state was obtained in ABS samples with 9.441 Ra and significant improvements in surface quality were observed with sanding processes.
